[CMake] recognizing shell in use

[Ajay Panyala]

That is because I have a custom target like

ADD_CUSTOM_TARGET(testc ALL
  COMMAND java ${PROJECT_BINARY_DIR}/test.java
  DEPENDS ${PROJECT_BINARY_DIR}/test.java
)

I want to build test.java only if it has been changed.

Since custom targets are always out-of-date, I wanted to have the
command inside the custom target like

COMMAND if( test.java has not been modified ) then java build/test.java; fi

The syntax of *if* differs between different shells. So I wanted to check
for
the shell first and use the appropriate IF syntax.


Thanks
Ajay
